The collection consists of Prigogine's holograph manuscripts and
typescripts dating from 1977 to 1980.
La Nouvelle Alliance, a book co-authored
with Isabelle Stengers, is represented by three typescripts. Two of the
typescripts are in English and contain holograph revisions; the earlier version
is titled
Dialogue with Nature. Notes for the sixth
chapter of a later book,
Order out of Chaos, are also present.

"Order out of Chaos" was also the title of a
lecture given by Prigogine at the University of Texas in 1977; audio recordings
and a transcript of the lecture are present in the collection. Other lecture
materials include a holograph manuscript and audio recording of
"From Being to Becoming," a series of three
lectures given at the University of Texas in 1978; a 1979 lecture given at the
University titled
"Einstein: Triumphs and Conflicts"; a
typescript of
"Aspects of Chemical Evolution," presented at
the 1980 Solvay Conference in Chemistry in Washington, D. C.; and a typescript,
list of references, notes, and transparencies from
"Probing into Time: The 1980 Aharon Katzir-Katchalsky
Lecture" at the Weizmann Institute in Rehovat, Israel.
"Probing into Time" is also the title of an
article that appeared in
Discovery in September 1980, and a
typescript of that work is present in the collection.
